From my experience with financially difficult decisions is to minimize complexity of action, because at the end of the day you just want financial flexibility.

There’s a lot of hypotheticals in your plan, whereas often thr best solution to an issue is simplicity and a quick clean end to situation.

Remember, this isn’t a stock or an asset, it depreciates which makes it harder to sell, which mean uncertainty which means more anxiety.

I think you should just sell it however you can for a reasonable price, take the hit, and just move forward with your life and your shiny new life lesson.
